What is an .swf file and what do I open it with? Are we able to save our game with the new version? I just found how to get the tentacle monsters quicker.
.swf stands for "Shock Wave Flash" and means the game was programmed to be played in a Flash Player. You'll want to search for a standalone flash player as most browsers no longer have native flash support. I believe Adobe's is still available through a quick google search.
